Despite being the foundation of India’s economy, agriculture remains a sector with underpaid workers. Farmers face a complex environment with variable climates, diverse soil conditions, and water scarcity. Additionally, there is a gap in adopting technological advancements. India’s massive and ever-growing population necessitates a more productive agricultural sector. To achieve optimal yields, integrating modern technologies becomes essential. The Internet of Things (IoT) offers a powerful solution for data exchange between devices over the Internet, minimizing human intervention. This technology can be harnessed to design smart irrigation systems that conserve water and automate operations. This chapter outlines an IoT-based irrigation system implemented using the ThingSpeak cloud platform. Sensors collect real-time field data on crucial parameters like soil moisture, temperature, and humidity. This data is then stored and analyzed on ThingSpeak, allowing farmers to make informed irrigation decisions through a mobile app.
